I. [Product Description]
Tosylate-PEG-NBD (Tosylate-Polyethylene Glycol-Nitrobenzoxadiazole) is a multifunctional organic intermediate with both high catalytic activity and molecular designability. It is widely used in the synthesis of pharmaceutical intermediates and the development of functional materials. The Tosylate group in its structure provides excellent leaving ability, the NBD fluorescent group endows the molecule with a labeling function, and the PEG segment enhances water solubility and biocompatibility, making it suitable for molecular connection and modification in complex systems.
